This is a huge sweeping generalization statement that implies no one can build secure digital hardware. Wrong.
@elonmusk 's view may apply to US n other places - where they use regular compute platforms to build Internet connected Voting machines.
But Indian EVMs are custom designed, secure and isolated from any network or media - No connectivity, no bluetooth, wifi, Internet. ie there is no way in. Factory programmed controllers that cannot be reprogrammed.
Electronic voting machines can be architected and built right as India has done. We wud be happy to run a tutorial Elon 😁
